let's start with proof that there is one first

If i put the spring in between two opposite tensions -the spring needs to be rigid in space to be a spring - if the coil just expands - its not a working mechanical spring

gg you're stupid


a body in which the distance between any pair of points remains fixed under all forces;
you put this in red
and i thought it would be obvious if you reverse it the spring compresses and the distance changes sorry

What a surprise - you cherry picked the definition on a word to make it fit your bias, ha. What word would you suggest that could efficiently describe the difference between the properties of a bowl of Jello and and that of an Ice cube are the exact same because they're both made of water, because that is what you doing when you're saying a slinky is a spring. And rigid itself does not always mean just completely inflexible ever - as in only the man of steel could bend it. In mechanics it referes to being able to transfer tension from one end to the other, that it remains rigid in space.

I notice you didn't include these definitions of that word because you're completely intellectual dishonest to yourself and everyone.

4. exacting; thorough; rigorous:
a rigid examination.
5.
so as to meet precise standards; stringent:
lenses ground to rigid specifications.
6.
Mechanics. of, relating to, or noting a body in which the distance between any pair of points remains fixed under all forces; having infinite values for its shear modulus, bulk modulus, and Young's
modulus.

A Slinky does not remain rigid in space when tension is applied at opposite ends and is therefore not a spring.


Are you retarded? The red highlight is the exact opposite for what happens with springs. Take any spring and push or pull the ends, the distance between every coil will change. That's the whole point of springs, that's how they work.

Here's a picture to help your feeble mind grasp what happens to springs. Fx is a "force", the same word as in your red highlight where it says "all forces".
Lo is the initial distance between two ends of the spring. In other words, it's a "distance between a pair of points".
Lx is the distance between the same points after a force is applied.

As we can see, "the distance between a pair of points does not remain fixed under a force". In a rigid body, "the distance between a pair of points remains fixed under a force". Do you see the conflict here?

So in this case - it is rigid before you apply tension isn't it? See how you move the goalposts to fit your bias? I bet you've had this problem your whole life haven't you?

And in the example you provided it is applying the force thought the entire spring , its not segmented.

So funny how whether a slinky is a useless toy for children or a mechanical spring is the great debate on jsp? Whoda thought?

I guess it s not so useless really.

The definition of rigid includes the words "under all forces". The word describes how an objects behaves when a force is applied, so talking about an object "before it experience a force" is nonsensical.

Besides, by your retarded definition every object in the universe can be "rigid". A slinky sitting on the ground is just as "rigid" until you pick it up.

You're just comparing to spring from the start point to the end point - but if you take any particular point of time along that continuous action, the spring is still rigid at that point and applying its tension throughout it's entire length.

except the thread has near 40,000 views, and is the most popular thread in the music section, I just dont need people spamming their bs opinions, that's for children who need emotional support and constant reinforcement that people like them.

What a Stuart Smalley :rofl:

Since your point isjust a simple strawman, its obvious you're the troll here
